[primgen] Make primgen "portable" again

Primgen is vendored into Ibex and there we don't have the full directory
structure of OpenTitan, but only the primgen folder. To go back into a
state where we can vendor primgen into Ibex, this commit does two
things:

* Move the vendored-in Verible Python code into a subdirectory of
  primgen. No functional change.
* Remove the dependency on check_tool_requirements. We only use that
  dependency to show the version number of Verible in human-readable
  output for eventual debugging. I don't think we've ever used this
  information, so I'm just removing it for now to keep things simple,
  instead of reimplementing parts of the logic inside primgen.
